Care Guide
Dorymyrmex bureni, commonly known as the pyramid ant, is a lively and fast-moving species native to the southern United States and parts of Latin America. These ants are monomorphic, meaning all workers are roughly the same size, ranging from 2.5 to 3.5 mm, while the queen is slightly larger at 4–5 mm. A mature colony can reach a population of 1,000 to 5,000 workers, forming impressive, cone-shaped mounds that give the genus its common name. Their energetic foraging style and visible surface activity make them a fascinating species to observe for keepers ready for a bit more challenge.
The diet of Dorymyrmex bureni is versatile. In the wild, they feed on honeydew from aphids and scale insects, as well as small arthropods. In captivity, they thrive on a mix of sugar water, honey water, or a liquid ant nectar, supplemented with protein sources such as small feeder insects like fruit flies, pinhead crickets, or chopped mealworms. A balanced diet is essential for steady brood production and colony growth. Unlike some seed-harvesting species, these ants do not store dry food, so offerings should be fresh and consistent.
Care difficulty
Keeping Dorymyrmex bureni is best suited for intermediate ant keepers. While the claustral foundation of new colonies is relatively straightforward, the species is sensitive to dryness and requires careful humidity management. Their rapid pace and sensitivity to disturbances also mean they are less forgiving of neglect than hardier beginner species. However, their active above-ground foraging and lack of hibernation needs make them an excellent year-round display colony for those with some experience.
Housing
A formicarium for Dorymyrmex bureni should provide a nest chamber that maintains stable humidity between 50–70% and a temperature range of 24–28°C. These ants do not require hibernation, so consistent warmth is important for year-round development. They are excellent escape artists, so a well-sealed outworld with a smooth barrier or fluon is recommended. The outworld should offer a shallow water source and feeding area, as these ants are often seen drinking droplets placed on a flat surface. Provide a substrate in the outworld that mimics their natural dry, sandy habitat, as they enjoy digging and rearranging their surroundings.
First days after purchase
Upon receiving your Dorymyrmex bureni colony, place the formicarium in a quiet, dimly lit area and allow the ants to settle for at least 24 hours. Avoid unnecessary vibrations or bright light, as this can cause stress. Provide a small drop of sugar water and a tiny piece of protein, then observe from a distance. If the queen and workers seem calm and begin grooming or exploring, the colony is adjusting well. Over the next few days, gradually increase feeding portions and check humidity levels daily. Patience is key—these ants may be fast, but they need time to acclimate to their new home. Once established, their constant activity and mound-building behavior will reward your careful attention.
